I will definitely have to say scorpio rising and/or pluto aspecting the ascendant. This makes people project their dirt on the person with these placements.and yes i think you are right,mars/pluto can is directly related to the issue but i feel that mars/pluto is bullying on steroids usually,as it is very often found in the charts of both criminals and victims!
...I actually think that extends to anyone who has Pluto prominent or highly active in their chart in some way, whether it's aspecting angles, luminaries, or inner planets as well.
Pretty much all my life at various points I've been singled out, demonized and targeted by people. As a kid and even up until the last few years of my life, I largely blamed myself for it because I didn't know any better, I didn't know anything about projection so I went based on the external feedback I was getting and figured that since I keep having such negative experiences with people, I
must be the bad one and the problem. I spent a lot of time beating myself up mentally and jumping hoops trying to please people and change myself because of it.
Once I learned a bit about human nature and the human psyche and my astrological knowledge grew, then I sat down and did the math about my own behavior. I realized there was nothing I was doing to justify any of the hostile and/or predatory behavior I'd been on the receiving end of, and that it had to be something else going on, something that had nothing to do with me.
I think Plutonian people end up being lightning rods unfortunately. A lot of people have unresolved Plutonian issues, some that aren't even aware they have those issues in the first place, or they've deeply repressed them. So then a Plutonian person walks past them and they immediately project all that energy onto them and in their mind, it suddenly becomes that other person that is the problem. At which point they prey on and terrorize the Plutonian person, in an subconscious attempt to fix
themselves.
If they manage to successfully beat the Plutonian person into submission, (whether through words, fists or some other means), they go into a state of peace and contentment, which doesn't last long because, unbeknownst to them, that other person wasn't the problem in the first place, the problem is what's going on
inside them, which still isn't resolved or healed. Those issues then eventually become a primary problem again and usually get vomited out onto the next Plutonian person that comes along and they then continue the cycle.
Once I really understood this, my whole approach to these situations, changed. Rather than try to defend myself, thinking that would make them back off (it doesn't; if anything, they use it as confirming 'evidence' in their own head that you
are the problem and continue or even escalate their abuse) I know now to just completely ignore it and outright refuse to respond or engage them in any way. When you just don't acknowledge them at all they eventually move on and, unfortunately, target someone else.
